'struct configfs_item_operations' and 'configfs_group_operations' are not
modified in this driver.

Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  27503	  12184	    256	  39943	   9c07	drivers/pci/endpoint/pci-ep-cfs.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  27855	  11832	    256	  39943	   9c07	drivers/pci/endpoint/pci-ep-cfs.o
